Answer:

The correct answer would be - oxygen will passively diffuse into the cells.

Explanation:

As the oxygen molecules are very small and has no polarity or no charge they show the passive diffusion through the plasma membrane from the higher concentration to lower concentration inside the cell.

In the lungs the oxygen diffuses out the air sacs into the blood as the air sacs of lungs have higher concentration of oxygen than the blood stream and as the various cells perform the aerobic cellular respiration the concentration of the oxygen inside of the cell become low to the blood so oxygen diffuses into cells.

Thus, the correct answer is - oxygen will passively diffuse into the cells.

Why do you suppose the structural polysaccharide cellulose does not contain branches?
Igoryamba

This is because cellulose is composed of beta glucose units, unlike starch that is formed using alpha-glucose units. The beta acetal linkage between units allows for linear chains hence branches are unlikely. The alpha acetal linkages allow for spiral chains. The beta glucose is good for structural polysaccharides because it allow for best interaction between polymer chains and increases the integrity and strength of the cells wall.

Explanation:

It is important we understand what is immunoglobulin test.

Immunoglobulins, also known as antibodies, are measured by the test carried out in the blood. Antibodies are proteins produced by the immune system to combat pathogens such as viruses and bacteria that cause disease. Immunoglobulins are proteins produced by the body to combat various substances.

The immunoglobulin assay tests three forms of immunoglobulins in total. IgG, IgM, and IgA are the three types of antibodies. IgG, IgM, and IgA levels that are too low or too high may indicate a severe health condition.

Thus, from the above question; the next step that would be appropriate is:

Assuming the test uncovers an increase in immunoglobulin, it demonstrates contamination or infection. Thus, a fitting treatment ought to be begun against the infection.  

However, suppose the text doesn't uncover an increase in immunoglobulin and assuming he shows manifestations of symptoms, then the brain biopsy ought to be performed to affirm the diagnosis of kuru.

The citric acid cycle is the metabolic center of the cell. It is the doorway to the aerobic metabolism of any molecule that can be changed into an acetyl group or a part of the citric acid cycle. The cycle is additionally a significant wellspring of prototype for building blocks of numerous different molecules like amino acid and nucleotide base.

Thus, the best accurate statement is: Option C
